If set D is not the empty set but is a subset of set E, then which of the following is true?

MrRa [10]

D∩E=D This is because since D is a subset of E then the elements they will have in common are the elements in D and D is not a null set

You take out a student loan for $80,000 with 2.75% annual interest to pay for your first year of college. This loan will cover a

yKpoI14uk [10]

Exponential growth equation would be

Amount= 80,000 (1+2.75/100) ⁴

At the end of 4 years I would have to repay an amount of $ 89,169.70

Step-by-step explanation:

Since, the amount is loaned it would vary exponentially i.e. in a compounding manner.

We know that for compound interest, the equation is written as-

Amount= principal(1+r/100) ˣ

Where r- rate of interest which is 2.75% annually

And x= time period= 4 years as in the question

Principal= $ 80,000

Therefore, Equation becomes-

Amount= 80,000(1+2.75/100) ⁴

On solving this Amount would equal $ 89,169.70

Hence, at the end of 4 years I would have to repay an amount of $ 89,169.70.

Divide. Express the quotient in simplest form.<br> x^2−x−12/2x^2÷x^2+x−6/2x^3

sertanlavr [38]

Hey there!

These are technically expressed as fraction. When you divide a fraction by another, you can replace the second fraction with its reciprocal and you can now multiply the fractions together instead.

$\frac{x^2-x-12}{2x^2} / \frac{x^2+x-6}{2x^3}$

$\frac{x^2-x-12}{2x^2} * \frac{2x^3}{x^2+x-6}$

Now, just multiply across the top and the bottom. You can first cancel out any terms that are repeated or similar.

$\frac{12}{2x^2} * \frac{2x^3}{-6}$

$\frac{2}{x} * \frac{1}{-1}$

$\frac{2}{-x}$

Your answer will be $\frac{2}{-x}$ .

Hope this helped you out! :-)
